Document Type and Number:
WIPO Patent Application WO/2020/155802
Kind Code:
A1
Abstract:
Disclosed is a train set emergency power supply method, applied to a train set emergency power supply apparatus. The method comprises: determining whether an emergency traction signal is acquired; when the emergency traction signal is acquired, starting an emergency traction mode, and controlling a power battery of a train set emergency power supply apparatus to supply power to a traction converter; acquiring working condition data of the traction converter of the train set emergency power supply apparatus; determining whether the traction converter is in a failure state on the basis of the working condition data; when the traction converter is in the failure state, acquiring identification information of the train set emergency power supply apparatus; outputting prompt information for representing that the traction converter matching the identification information has a failure; and determining whether a switching signal is detected, and if so, controlling the power battery of the train set emergency power supply apparatus to switch to a preset power supply branch of a traction converter of another train set emergency power supply apparatus. When a traction converter of a train set emergency power supply apparatus has a failure, a power battery thereof can supply power to another traction converter. The present invention further relates to a train set emergency power supply system.
